Puette, a former Chicago theater actress and go-to gal for playing "dying woman in bed," stars as Jessica Andover—that woman dying in bed at the end of "There Will Be Blood."

Puette is sworn to secrecy about the bizarre ritual that's obviously taking place, but viewers just need to add up all the clues from the episode—Jessica's bloodied arm, the dead man on the gurney and the "doctor" standing over him cleaning a needle.

There will be blood transfusions, right?

"Her husband has contrived a really twisted way to keep his beloved wife alive," Puette said. "Jessica becomes key to the survival of the entire town of Willoughby, and of Rachel (Elizabeth Mitchell) and Miles (Billy Burke) and the rest of them."

They're all fighting for their survival in next week's episode, "Love Story." In the preview above, creepy Titus (Matt Ross) and the doctor strap Miles onto that gurney, and Titus' forces attack Willoughby, shooting Rachel with an arrow.

The episode just might get its title from the story of Titus and Jessica.

"He really does love her a great deal. It's just the way he loves her is really twisted," Puette said of the David Rambo written episode. "It's a love story, like in the worst sense of the term. It's really dark."

If you're a fan of "True Blood," Puette's bedridden scene Wednesday might have reminded you of her scenes in the Season 5 "True Blood" episode, "Somebody That I Used to Know." Puette played Sarah Compton-Harris, the dying daughter of vampire Bill (Stephen Moyer) who begged him to turn her.

"It was so, so freaky because … my costume is a very similar color, I'm clearly sick in bed, and it was an old-fashioned kind of setting--something that looks like a period piece. It did seem very similar," she said. "Maybe I'm going to just corner the market on playing dying ladies."

Does her character die this time? Keep watching "Revolution" at 7 p.m. CT Wednesdays on NBC. Puette will answer fan questions during the West Coast airing of the Oct. 9 episode. Tweet her @deborahpuette.Want more? Discuss this article and others on Show Patrol's Facebook page.
